I’m assuming your engine cuts off during fueling by your description of the problem.if so,your engine should be off for refueling.Your cars computer is monitoring the fuel tank pressure while the car is running..when you open the gas cap it’s sets a code for loss of pressure,assumes the gas cap is gone and shuts the car down for safety reasons.CAR OFF DURING FUELING.hope this helps.
